1. THUECON® CEM 40 F
Reliable Corrosion Protection
- Mineral Coating System for District Heating
Pipelines -
for more than 25 years
2. What is THUECON®
THUECON® is a 2-component solvent-free mineral coating which hardens
Product hydraulically. The combination of selected natural minerals plus a high-grade
reactive fluid component produces the ready-for-use mixture THUECON®
In 1996 Manfred Förster, our chief development officer, has developed
THUECON® for restoration of district heating pipelines and against
History corrosion. The patented product was used for the first time in 1998 in
Bucharest in Romania.
Since 1998 THUECON® has a scientific expertise by the district heating
research institute. Up to now it has been applied for the modernisation of
district heating systems of a length of 30 kilometers in total. In Zelenograd
References near Moscow, 3000 meters of district heating pipelines have been
rehabilitated successfully in 2001. By now THUECON® can rely on more
than 10 years of experience and successful modernisations of pipelines.

3. Key in-pipe challenges
Water temperatures up to 100 C,
water vapour temperatures up to High oxygen saturated water
180 C
Extrem in-pipe corrosion
1. After 20-25 years perforation from
corrosion
2. Complete blackout of heating system
3. High, unplanned costs for the operator

7. Cleaning
To ensure a high adhesion the pipe wall must be free of any separator
substances such as dust, oil, grease, loose particles and instable coats.
The innovative cleaning system with water super pressure more than 1300 bar
and 100 l of water per minute removes all loose particles and separator
substances from the pipe wall. Even the depths of corrosion are cleaned by the
high-pressure water.
The cleaned pipe wall guarantees secure and long lasting adhesive properties
for the THUECON® coating to steel.
Through the position of the cleaning nozzles and the resulting air-stream the
removed material and the waste water are transported towards the "black side"
out of the pipe. The clean "white side" is simultaneously dried by the air
stream.

8. Application method
There are numerous possibilities for the application of THUECON® :
centrifugation by the use of a pneumatic motor with a lamellar head, manually or
mechanically. The most common method for pipelines is the coating with
centrifugal device.
After a couple of minutes mixing time the finished mixture THUECON® can be
used for application for a few hours. The material is transported under
pressure through the material delivery hose to the centrifugal device. By use of
steplessly adjustable drawing technology the material hose and the centrifugal
device are pulled out of the pipe with a speed adjusted to the diameter of the
pipe. This speed determines the exact thickness of the coating on the inner wall
of the pipe.
The hydro-head of the centrifugal device is powered with 3000 up to 5000
rotations per minute by use of compressed air and throws the material on the
inner wall of the pipe. The high-rotation of the hydro-head guarantees a smooth to
orange skin-like appearance of the surface.
After 24 hours the primary curing is achieved and the pipeline can be put
back into operation.
